Actually, the more I thought about the situation, the less I felt like I
understood what you were seeing. I don't think my explanation gels with you
seeing things that seem to "disappear" -- there really shouldn't be any gaps.

Any chance you can provide a shell script to reproduce exactly what you're

I've been concerned for some time that there might be a bug in our
repos_get_locations() code (based on a weird bug report I've been trying to
field over in the ViewVC project). So a good repro recipe from you could be
key to this research.

Thanks (in advance).
